Description
FIELD OF THE INVENTION
The present invention relates to a method for manufacturing a shoe
embryo and an associated shoe embryo, and particularly to a method
for manufacturing a shoe embryo tailored from a tubular fabric and
an associated shoe embryo.
BACKGROUND OF THE INVENTION
A shoe in general includes two parts--a shoe upper and a sole. The
sole is secured below the shoe upper. A material of the shoe upper
focuses on providing comfort and firmness. For example, there are
diversified choices of materials having different properties for
the shoe upper of sports shoes. The so-called "different
properties" include tensile resistance, wear resistance,
flexibility, air permeability, compressibility, moisture absorption
and quick perspiration drying. More specifically, the shoe upper
may be formed by materials including textiles, leather, synthetic
leather or rubber. Common materials for making the commercial shoe
upper include textiles, polymer foams, polymer sheets, leather and
synthetic leather. However, one of the most common base materials
for making the shoe upper or sports shoes or the shoe upper of
casual shoes is fabrics manufactured from yarns of composite
materials by a weaving machine. Once such fabric is formed
three-dimensionally, a shoe embryo is formed. One main reason that
the shoe embryo is extensively applied as the base material of
sports shoes or casual shoes is that, the shoe embryo can be given
different properties in different areas, including functional
purposes of tensile resistance, wear resistance, flexibility, air
permeability, compressibility, comfort, and moisture absorption. It
is thus known from above, the shoe embryo is a semi-finished
product before such shoes are completely manufactured. That is to
say, the shoe embryo requires further subsequent processes, such as
inserting a vamp model for shaping, surface ironing,
gluing/heating/pressurizing, paint spraying and dye, sole gluing
and extracting the vamp model. In current technologies for the shoe
embryo, e.g., the Taiwan Patent No. M515792, a three-dimensional
shoe embryo is generally formed by combining, splicing and sewing
multiple different planar fabrics. However, the technical means for
manufacturing the shoe embryo suffers from certain drawbacks that
need to be overcome. First of all, to re-organize, splice and sew
different planar fabrics to form a three-dimensional shoe embryo,
an operating staff is required to have sophisticated techniques and
capabilities, which can only be achieved through professional
tailor training, hence inevitably leading to significant manpower
costs for manufacturers. Secondly, when the planar fabrics are
re-organized, spliced and sewn, deformation of the shoe embryo and
splicing deviations may likely occur due to human factors such as
alignment errors, in a way that the yield rate of the shoe embryo
may not be effectively increased and material costs are
substantially increased for manufacturers. Thirdly, processes for
combining and splicing the planar fabrics are tedious, which limits
both production efficiency and production throughput.
SUMMARY OF THE INVENTION
In view of the above drawbacks of known technologies, it is a
primary object of the present invention to shorten work hours,
boost production efficiency, increase product yield rate and reduce
manpower costs to achieve enhanced industry competitiveness.

With the technical solution above, the present invention achieves
effects below as opposed to currently known technologies. First of
all, as the tubular fabric of the present invention is directly
sewn using a three-dimensional shape, and involves no
re-organizing, splicing and sewing processes. In the process of
trimming and overlocking the tubular fabric in the tubular
three-dimensional shape, the issue of error and deviation are
unlikely to occur, such that not only the yield rate of the shoe
embryo can be promoted without causing a waste in material costs,
but also such process of trimming and overlocking can be performed
by operators without professional tailor training, thereby helping
in reducing manpower costs. Secondly, in the present invention,
auxiliary lines apparently visible are woven on the tubular fabric
to assist a process operator to perform trimming and overlocking.
Thus, an operator may promptly position and process according to
exact positions of these auxiliary lines to further optimize
production efficiency. Thirdly, with the shoe embryo that is
manufactured from the tubular fabric in a tubular three-dimensional
shape, re-organizing and splicing processes in currently known
technologies can be eliminated. As the processes are simplified,
the work hours required for production are also shortened, which
further accounts for a factor for effectively enhancing production
efficiency and industry competitiveness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Details of a method for manufacturing a shoe embryo tailored from a
tubular fabric and a shoe embryo of the present invention are given
in the non-limiting embodiments with the accompanying drawings
below.
FIG. 1 to FIG. 11 show schematic diagrams of a first embodiment. In
this embodiment, a tubular fabric 1 is woven from at least two
yarns. As seen from FIG. 1 to FIG. 5, the tubular fabric 1 has its
one end woven with a toe portion tailor auxiliary line 40 and the
other end woven with a heel portion tailor auxiliary line 30. An
ankle portion tailor auxiliary line 20 is woven at a position
between the heel portion tailor auxiliary line 30 and the toe
portion tailor auxiliary line 40 and near the heel portion tailor
auxiliary line 30. The tubular fabric 1 is sequentially defined
into a toe portion trimmed region 41, an ankle portion trimmed
region 21 and a heel portion trimmed region 31 by the toe portion
tailor auxiliary line 40, the ankle portion tailor auxiliary line
20 and the heel portion tailor auxiliary line 30, respectively.
First of all, the ankle portion trimmed region 21 is trimmed and
removed, and an overlock process is performed according to the
ankle portion tailor auxiliary line 20 to form an ankle opening
overlock line 211 at the tubular fabric 1, as shown in FIG. 6. The
heel portion trimmed region 31 is trimmed and removed, and an
overlock process is performed according to the heel portion tailor
auxiliary line 30 to form a heel overlock line 311 at the tubular
fabric 1, as shown in FIG. 7. Next, a part below the heel overlock
line 311 is folded to form a concave crease 312 and a revealed
crease 313, such that a sole trimmed region 314 is defined at the
tubular fabric 1 by the concave crease 312 and the revealed crease
313, as shown in FIG. 8. Next, the sole trimmed region 314 is
trimmed and removed, and an overlock process is performed according
to the concave crease 312 to form a sole overlock line 315 at the
tubular fabric 1, as shown in FIG. 9. The toe portion trimmed
region 41 is then trimmed and removed, and the toe portion tailor
auxiliary line 40 is combined in an overlapping manner for an
overlock process to form a toe cap overlock line 411. Further, the
tubular fabric 1 is shaped into a shoe embryo 10 including an ankle
portion 22, a heel portion 32, a toe cap portion 42 and a sole
portion 50, as shown in FIG. 10. The shoe embryo 10 may then be
used for subsequent shoe manufacturing processes. Alternatively, in
FIG. 11, the shoe embryo 10 may be entirely turned inside out for
subsequent shoe manufacturing processes. It should be noted that,
concerning the sequences for forming the overlock lines by the
trimming and overlock processes, the toe cap overlock line 411, the
ankle opening overlock line 211, the heel overlock line 311 and the
sole overlock line 315 may be sequentially formed by the respective
trimming and overlock processes. Further, the tubular fabric 1 is
woven from at least two differently-colored yarns, and the ankle
portion tailor auxiliary line 20, the heel portion tailor auxiliary
line 30 and the toe portion tailor auxiliary line 40 may be
selected and woven from one of the yarns used for weaving the
tubular fabric 1. Further, the ankle portion tailor auxiliary line
20, the heel portion tailor auxiliary line 30 and the toe portion
tailor auxiliary line 40 may be selected and woven from one of the
colors of the yarns used for weaving the tubular fabric 1. That is
to say, the ankle portion tailor auxiliary line 20, the heel
portion tailor auxiliary line 30 and the toe portion tailor
auxiliary line 40 may be woven from one of the yarns or one of the
colors of the yarns used for weaving the tubular fabric 1. It
should be noted that, the toe portion tailor auxiliary line 40
includes an arched above-toe auxiliary segment 401, and an arched
below-toe auxiliary segment 402 connected to two ends of the
above-toe auxiliary segment 401. The length of the above-toe
auxiliary segment 401 is greater than the length of the below-toe
auxiliary segment 402, which is beneficial for the toe cap overlock
line 411 to form within the range of the sole portion 50. Thus,
when later incorporated with a sole material (a generally known
shoe manufacturing process, not shown in the drawing), the toe cap
overlock line 411 may be easily concealed and adorned.
Again referring to FIG. 1, FIG. 10 and FIG. 11, the shoe embryo 10
in the drawings according to the first embodiment is tailored and
manufactured from a tubular fabric 1, which is woven from at least
two yarns. The tubular fabric 1 has its one end woven with the toe
portion tailor auxiliary line 40 and its other end woven with the
heel portion tailor auxiliary line 30, and the ankle portion tailor
auxiliary line 20 is woven at a position between the heel portion
tailor auxiliary line 30 and the toe portion tailor auxiliary line
40 and near the heel portion tailor auxiliary line 30. The tubular
fabric 1 is sequentially defined into the toe portion trimmed
region 41, the ankle portion trimmed region 21 and the heel portion
trimmed region 31 by the toe portion tailor auxiliary line 40, the
ankle portion tailor auxiliary line 20 and the heel portion tailor
auxiliary line 30, respectively. The shoe embryo 10 includes the
sole portion 50, the toe cap portion 42 located at one end of the
sole portion 50, the heel portion 32 located at the other end of
the sole portion 50, and the ankle portion 22 located above the
sole portion 50 and near the heel portion 32. The ankle portion 22
includes the ankle opening overlock line 211 formed by trimming the
ankle portion trimmed region 21 of the tubular fabric 1 and
overlocking. The heel portion 32 includes the heel overlock line
311 formed by trimming the heel portion trimmed region 31 of the
tubular fabric 1 and overlocking, and the sole overlock line 315
formed by folding below the heel overlock line 311 and overlocking.
The toe cap portion 42 includes the toe cap overlock line 411
formed by trimming the toe portion trimmed region 41 of the tubular
fabric 1 and overlocking. Thus, the shoe embryo 10 may be used for
shoe manufacturing processes.
FIG. 12 to FIG. 19 show schematic diagrams of a second embodiment
of the present invention. In this embodiment, the tubular fabric 1
is woven from at least two yarns. As seen from FIG. 12 to FIG. 14,
the tubular fabric 1 has its one end woven with a toe portion
tailor auxiliary line 40 and the other end woven with the heel
portion tailor auxiliary line 30. The ankle portion tailor
auxiliary line 20 is woven at a position between the heel portion
tailor auxiliary line 30 and the toe portion tailor auxiliary line
40 and near the heel portion tailor auxiliary line 30. The tubular
fabric 1 is sequentially defined into the toe portion trimmed
region 41, the ankle portion trimmed region 21 and the heel portion
trimmed region 31 by the toe portion tailor auxiliary line 40, the
ankle portion tailor auxiliary line 20 and the heel portion tailor
auxiliary line 30, respectively. It is clearly seen that the path
design of the ankle portion tailor auxiliary line 20 of the second
embodiment is different from the path design of the ankle portion
tailor auxiliary line 20 of the first embodiment (also referring to
FIG. 1 to FIG. 5). Thus, to satisfy market demands, the ankle
portion trimmed region 21 defined in the second embodiment and the
first embodiment may generate different shapes and variations.
First of all, the ankle portion trimmed region 21 is trimmed and
removed, and an overlock process is performed according to the
ankle portion tailor auxiliary line 20 to form the ankle opening
overlock line 211 at the tubular fabric 1, as shown in 15. The heel
portion trimmed region 31 is trimmed and removed, and an overlock
process is performed according to the heel portion tailor auxiliary
line 30 to form the heel overlock line 311 at the tubular fabric 1.
Because the path design of the heel portion tailor auxiliary line
30 does not connect to the path of the ankle portion tailor
auxiliary line 20, after the ankle opening overlock line 211 and
the heel overlock line 311 are formed by sequentially trimming and
overlock processes, a joint of the ankle portion 22 and the heel
portion 32 may be extended to form a shoe upper 33, as shown in
FIG. 16. A part below the heel overlock line 311 is folded to form
the concave crease 312 and the revealed crease 313, such that the
sole trimmed region 314 is defined at the tubular fabric 1 by the
concave crease 312 and the revealed crease 313, as shown in FIG.
17. Next, the sole trimmed region 314 is trimmed and removed, and
an overlock process is performed according to the concave crease
312 to form the sole overlock line 315 at the tubular fabric 1, as
shown in FIG. 18. The toe portion trimmed region 41 is then trimmed
and removed, the toe portion tailor auxiliary line 40 is combined
in an overlapping manner for an overlock process to form the toe
cap overlock line 411. Further, the tubular fabric 1 is shaped into
the shoe embryo 10 including the ankle portion 22, the heel portion
32, the toe cap portion 42 and the sole portion 50, as shown in
FIG. 19. The shoe embryo 10 may then be used for subsequent shoe
manufacturing processes. It should be noted that, concerning the
sequences for forming the overlock lines by the trimming and
overlock processes, the toe cap overlock line 411, the ankle
opening overlock line 211, the heel overlock line 311 and the sole
overlock line 315 may be sequentially formed by the respective
trimming and overlock processes. Further, the tubular fabric 1 is
woven from at least two differently-colored yarns, and the ankle
portion tailor auxiliary line 20, the heel portion tailor auxiliary
line 30 and the toe portion tailor auxiliary line 40 may be
selected and woven from one of the yarns used for weaving the
tubular fabric 1. Further, the ankle portion tailor auxiliary line
20, the heel portion tailor auxiliary line 30 and the toe portion
tailor auxiliary line 40 may be selected and woven from one of the
colors of the yarns used for weaving the tubular fabric 1. That is
to say, the ankle portion tailor auxiliary line 20, the heel
portion tailor auxiliary line 30 and the toe portion tailor
auxiliary line 40 may be woven from one of the yarns or one of the
colors of the yarns used for weaving the tubular fabric 1. It
should be noted that, the toe portion tailor auxiliary line 40
includes the arched above-toe auxiliary segment 401, and the arched
below-toe auxiliary segment 402 connected to the two ends of the
above-toe auxiliary segment 401. The length of the above-toe
auxiliary segment 401 is greater than the length of the below-toe
auxiliary segment 402, which is beneficial for the toe cap overlock
line 411 to form within the range of the sole portion 50. Thus,
when later incorporated with a sole material (a generally known
shoe manufacturing process, not shown in the drawing), the toe cap
overlock line 411 may be easily concealed and adorned.
Again referring to FIG. 12 and FIG. 19, the shoe embryo 10 in the
drawings according to the second embodiment is tailored and
manufactured from the tubular fabric 1, which is woven from at
least two yarns. The tubular fabric 1 has its one end woven with
the toe portion tailor auxiliary line 40 and its other end woven
with the heel portion tailor auxiliary line 30, and the ankle
portion tailor auxiliary line 20 is woven at a position between the
heel portion tailor auxiliary line 30 and the toe portion tailor
auxiliary line 40 and near the heel portion tailor auxiliary line
30. The tubular fabric 1 is sequentially defined into the toe
portion trimmed region 41, the ankle portion trimmed region 21 and
the heel portion trimmed region 31 by the toe portion tailor
auxiliary line 40, the ankle portion tailor auxiliary line 20 and
the heel portion tailor auxiliary line 30, respectively. The shoe
embryo 10 includes the sole portion 50, the toe cap portion 42
located at one end of the sole portion 50, the heel portion 32
located at the other end of the sole portion 50, and the ankle
portion 22 located above the sole portion 50 and near the heel
portion 32. The ankle portion 22 includes the ankle opening
overlock line 211 formed by trimming the ankle portion trimmed
region 21 of the tubular fabric 1 and overlocking. The heel portion
32 includes the heel overlock line 311 formed by trimming the heel
portion trimmed region 31 of the tubular fabric 1 and overlocking,
and the sole overlock line 315 formed by folding below the heel
overlock line 311 and overlocking. The toe cap portion 42 includes
the toe cap overlock line 411 formed by trimming the toe portion
trimmed region 41 of the tubular fabric 1 and overlocking. The
joint of the ankle portion 22 and the heel portion 32 is extended
to form the shoe upper 33. Thus, the shoe embryo 10 may be used for
shoe manufacturing processes.
FIG. 20 to FIG. 29 show schematic diagrams of a third embodiment of
the present invention. In this embodiment, the tubular fabric 1 is
woven from at least two yarns. As seen from FIG. 20 to FIG. 22, the
tubular fabric 1 has its one end woven with a toe portion tailor
auxiliary line 40, and the other end woven with a lining sealing
auxiliary line 12. The heel portion tailor auxiliary line 30 is
woven at a center between the toe portion tailor auxiliary line 40
and the lining sealing auxiliary line 12, such that a lining fabric
11 is defined between the heel portion tailor auxiliary line 30 and
the lining sealing auxiliary line 12. The ankle portion tailor
auxiliary line 20 is woven at a position between the heel portion
tailor auxiliary line 30 and the toe portion tailor auxiliary line
40 and near the heel portion tailor auxiliary line 30. The tubular
fabric 1 is sequentially defined into the toe portion trimmed
region 41, the ankle portion trimmed region 21, the heel portion
trimmed region 31 and a lining trimmed region 13 by the toe portion
tailor auxiliary line 40, the ankle portion tailor auxiliary line
20, the heel portion tailor auxiliary line 30 and the lining
sealing auxiliary line 12, respectively. First of all, the lining
trimmed region 13 is trimmed and removed, and the lining sealing
auxiliary line 12 is combined in an overlapping manner for an
overlock process to form a lining overlock line 14 at the tubular
fabric 1, as shown in FIG. 23. Using the heel portion tailor
auxiliary line 30 as a basis (i.e., when the heel portion tailor
auxiliary line 30 is woven, a segment serving as a basis may be
woven at an appropriate position of the heel portion tailor
auxiliary line 30), the lining fabric 11 is folded in reverse into
the tubular fabric 1, as shown in FIG. 24. The ankle portion
trimmed region 21 and a part of the lining fabric 11 corresponding
to the ankle portion trimmed region 21 are together trimmed and
removed, and an overlock process is performed jointly with the
lining fabric 11 according to the ankle portion tailor auxiliary
line 20 to form the ankle opening overlock line 211 at the tubular
fabric 1, as shown in FIG. 25. The heel portion trimmed region 31
and a part of the lining fabric 11 corresponding to the heel
portion trimmed region 31 are together trimmed and removed, and an
overlock process is performed jointly with the lining fabric 11
according to the heel portion tailor auxiliary line 30 to form the
heel overlock line 311 at the tubular fabric 1, as shown in FIG.
26. A part below the heel overlock line 311 is folded to form the
concave crease 312 and the revealed crease 313, such that the sole
trimmed region 314 is defined at the tubular fabric 1 by the
concave crease 312 and the revealed crease 313, as shown in FIG.
27. Next, the sole trimmed region 314 is trimmed and removed, and
an overlock process is performed according to the concave crease
312 to form the sole overlock line 315 at the tubular fabric 1, as
shown in FIG. 28. The toe portion trimmed region 41 is then trimmed
and removed, and the toe portion tailor auxiliary line 40 is
combined in an overlapping manner for an overlock process to form
the toe cap overlock line 411. Further, the tubular fabric 1 is
shaped into the shoe embryo 10 including the ankle portion 22, the
heel portion 32, the toe cap portion 42 and the sole portion 50 as
well as the lining fabric 11 therein, as shown in FIG. 29. The shoe
embryo 10 may then be used for subsequent shoe manufacturing
processes. It should be noted that, after the lining fabric 11 is
folded in reverse and placed into the tubular fabric 1, concerning
the sequences for forming the overlock lines by the trimming and
overlock processes, the toe cap overlock line 411, the ankle
opening overlock line 211, the heel overlock line 311 and the sole
overlock line 315 may be sequentially formed by the respective
trimming and overlock processes. Further, the tubular fabric 1 is
woven from at least two differently-colored yarns, and the lining
sealing auxiliary line 12, the ankle portion tailor auxiliary line
20, the heel portion tailor auxiliary line 30 and the toe portion
tailor auxiliary line 40 may be selected and woven from one of the
yarns used for weaving the tubular fabric 1. Further, the lining
sealing auxiliary line 12, the ankle portion tailor auxiliary line
20, the heel portion tailor auxiliary line 30 and the toe portion
tailor auxiliary line 40 may be selected and woven from one of the
colors of the yarns used for weaving the tubular fabric 1. That is
to say, the lining sealing auxiliary line 12, the ankle portion
tailor auxiliary line 20, the heel portion tailor auxiliary line 30
and the toe portion tailor auxiliary line 40 may be may be woven
from one of the yarns or one of the colors of the yarns used for
weaving the tubular fabric 1. It should be noted that, the toe
portion tailor auxiliary line 40 includes the arched above-toe
auxiliary segment 401, and the arched below-toe auxiliary segment
402 connected to the two ends of the above-toe auxiliary segment
401. The length of the above-toe auxiliary segment 401 is greater
than the length of the below-toe auxiliary segment 402, which is
beneficial for the toe cap overlock line 411 to form within the
range of the sole portion 50. Thus, when later incorporated with a
sole material (a generally known shoe manufacturing process, not
shown in the drawing), the toe cap overlock line 411 may be easily
concealed and adorned. Further, the lining sealing auxiliary line
12 includes an arched upper auxiliary segment 121, and an arched
lower auxiliary segment 122 connected to two ends of the upper
auxiliary segment 121. The length of the upper auxiliary segment
121 is greater than or equal to the length of the lower auxiliary
segment 122. That is to say, when length of the upper auxiliary
segment 121 is equal to the length of the lower auxiliary segment
122, the upper auxiliary segment 121 is allowed to more easily
combine with the lower auxiliary segment 122 in an overlapping
manner for an overlock process to form the lining overlock line 14
(as shown in FIG. 23). Since the lining overlock line 14 is placed
into the tubular fabric 1, the position of the lining overlock line
14 does not affect the appearance of the shoe embryo 10 formed from
the tubular fabric 1. Alternatively, the length of the upper
auxiliary segment 121 may also be greater than the length of the
lower auxiliary segment 122, such that the lining overlock line 14
may be formed on the sole portion 50 inside the shoe embryo 10. It
should be noted that, when the heel overlock line 311 of the third
embodiment of the present invention is sewn according to the path
of the second embodiment, the joint of the ankle portion 22 and the
heel portion 32 of the third embodiment may also be extended to
form the shoe upper 33, as shown in FIG. 16 to FIG. 19 of the
second embodiment.
Again referring to FIG. 20 and FIG. 29, the shoe embryo 10
according to the third embodiment is tailored and manufactured from
the tubular fabric 1, which is woven from at least two yarns. The
tubular fabric 1 has its one end woven with the toe portion tailor
auxiliary line 40, and its other end woven with the lining sealing
auxiliary line 12. The heel portion tailor auxiliary line 30 is
woven at the center of the toe portion tailor auxiliary line 40 and
the lining sealing auxiliary line 12, and the lining fabric 11 is
defined between the heel portion tailor auxiliary line 30 and the
lining sealing auxiliary line 12. The ankle portion tailor
auxiliary line 20 is woven at a position between the heel portion
tailor auxiliary line 30 and the toe portion tailor auxiliary line
40 and near the heel portion tailor auxiliary line 30. The tubular
fabric 1 is sequentially defined into the toe portion trimmed
region 41, the ankle portion trimmed region 21, the heel portion
trimmed region 31 and the lining trimmed region 13 by the toe
portion tailor auxiliary line 40, the ankle portion tailor
auxiliary line 20, the heel portion tailor auxiliary line 30 and
the lining sealing auxiliary line 12, respectively. The shoe embryo
10 internally includes the lining fabric 11, whose front end is
trimmed as the lining trimmed region 13 and is combined in an
overlapping manner and overlocked. The shoe embryo 10 further
includes the sole portion 50, the toe cap portion 42 located at one
end of the sole portion 50, the heel portion 32 located at the
other end of the sole portion 50, and the ankle portion 22 located
above the sole portion 50 and near the heel portion 32. The ankle
portion 22 includes the ankle opening overlock line 211 formed by
together trimming the ankle portion trimmed region 21 of the
tubular fabric 1 and the lining fabric 11 and overlocking. The heel
portion 32 includes the heel overlock line 311 formed by together
trimming the heel portion trimmed region 31 of the tubular fabric 1
and the lining fabric 11 and overlocking, and the sole overlock
line 315 formed by folding below the heel overlock line 311 and
overlocking. The toe cap portion 42 includes the toe cap overlock
line 411 formed by trimming the toe portion trimmed region 41 of
the tubular fabric 1 and overlocking. Thus, the shoe embryo 10 may
be used for shoe manufacturing processes.
